Hi, i'm doing a Transient simulation of a rotational solid enclosure by fluid. I configured the Solid Domain Motion to "Rotating" and the Domain interface to "Transient Rotor Stator"( with none pitch and CGI mesh connection). Also in Interface of fluid side I settled wall velocity relative to Mesh motion and Wall velocity by the angular velocity of solid domain. But, when in Post Solver the Interface of fluid side stay fixed, don't move as Interface of solid side . What i do to it move together in each timestep?

Nope, i changed the timesteps many times and only solid side rotate. Also the streamlines cross the solid side. I don't know if is right but i didn't put mesh deformation to solid domain neither rotate in fluid domain.
